This could prove interesting and useful for consortia that support distance students: Relais International announces D2D - Discovery to Delivery – the next generation resource sharing solution.
From the writeup at Library Technology guides: D2D allows users to search across multiple catalogs and targets to find items held by their library and library partners. Targets may include subscription databases and other options such as Google Books, WorldCat, and Amazon. The key to D2D is to optimize the user's ability to discover items of interest and get immediate access to or request delivery of the material with minimal or no intervention by library staff. Material may be supplied locally, from within a consortium or consortia or via traditional ILL. D2D supports the requesting, delivery and receipt of both returnable and non-returnable items. Delivery options include Ariel, Odyssey, Post-to-Web, email attachment, and fax.
